Mortars too stronk
So at the moment, mortars have gotten a bit too strong in the game. Once a HAB is spotted, one expert mortar player can totally shut the HAB down. Even if it's indoors, a good mortar player can alternate between the exits of the building and catch most players trying to leave it. Good mortar players also know where players are likely to be around the HAB, and can quickly drop some mortars there.
Additionally, UAV has made mortars significantly stronger. UAVs are a super easy to way to spot where enemy HABs exactly are.
There are a few different ways how this could be mitigated. Mortars' rate of fire could simply be reduced. A quite significant reduction would probably be in order. Or mortar shells could have a little bit of added randomness to their flight path.
Either way, currently a good mortar player can absolutely close down whole HABs, and it's just a single player. Effective mortaring should, in my opinion, require more than a single mortar. This would also mean that more supply is needed to be ran to keep the mortars firing. Two mortars after all use twice more ammo than one mortar.
